Thailand Public Holidays
Thailand has 18 national public holidays in 2026, observed across the whole country. Over the years covered here the calendar draws on 18 recurring holidays. 14 sit on the same calendar date every year, while 4 move (Announced per year). The same calendar applies nationwide, with no separate regional public holidays in this dataset.
Which public holidays does Thailand have?
Every recurring national public holiday, how its date is decided, and the date it lands on in 2025, 2026 and 2027. Dates are computed from the rule, so Easter-linked and moon-linked holidays are correct for each individual year.

Which Thai holidays are national and which are regional?
The 18 holidays above are national: they apply across Thailand rather than in one area only. This dataset holds no separate sub-national calendar for Thailand, so there is no regional layer to add. Individual towns and employers can still mark local days that are not national public holidays, and those are not covered here.
Which holidays move each year, and why?
4 of the 18 recurring holidays land on a different date each year. Here is the rule behind each group.
Same date every year (14)
The holiday is tied to one calendar date, so it lands on a different weekday each year but never changes date. In Thailand this covers New Year's Day, Chakri Memorial Day, Songkran Festival (day 1), Songkran Festival (day 2) and Songkran Festival (day 3), plus 9 more.
Announced per year (4)
There is no repeating rule. The date is set for that single year by an official announcement, which is why it has to be confirmed year by year and why it cannot be projected far ahead. In Thailand this covers Makha Bucha, Vesak Day, Asalha Puja and Buddhist Lent.
When is the next public holiday in Thailand?
The next 5 holidays on the 2026 calendar.
| Holiday | Date | Weekday |
|---|---|---|
| King Bhumibol Adulyadej Memorial Day | October 13, 2026 | Tuesday |
| King Chulalongkorn Day | October 23, 2026 | Friday |
| King Bhumibol Adulyadej's Birthday | December 5, 2026 | SaturdayWeekend |
| Constitution Day | December 10, 2026 | Thursday |
| New Year's Eve | December 31, 2026 | Thursday |

Frequently asked questions
How many public holidays does Thailand have?
Thailand has 18 national public holidays in 2026 and 14 in 2027. The total can differ from year to year because holidays that fall on a weekend sometimes gain a substitute day, and because moon-based and Easter-based dates occasionally shift in or out of a calendar year.
Which Thai public holidays fall on the same date every year?
14 of them: New Year's Day (January 1), Chakri Memorial Day (April 6), Songkran Festival (day 1) (April 13), Songkran Festival (day 2) (April 14), Songkran Festival (day 3) (April 15) and Coronation Day (May 4), plus 8 more. These are pinned to a calendar date, so only the weekday changes from year to year.
Which public holidays in Thailand change date each year?
4 do: Makha Bucha, Vesak Day, Asalha Puja and Buddhist Lent. The reasons are announced per year, so the Gregorian date has to be recalculated for every year rather than copied forward.
Are there regional public holidays in Thailand?
This dataset has no separate regional calendar for Thailand, so the national public holidays listed here apply countrywide. Individual towns can still observe local days that are not public holidays nationally.
What happens when a public holiday in Thailand falls on a weekend?
This dataset records no substitute days for Thailand, so every date listed here is the holiday itself rather than a replacement weekday. That is not the same as saying none is granted: a number of countries move a weekend holiday onto a working day under national labour law without that rule being captured in the underlying data, so check a local source whenever a holiday lands on a Saturday or Sunday.
How to use this page
Public holidays shape the working year in Thailand, closing many offices, banks and public services and shifting the rhythm of travel and shopping. If you are scheduling a delivery, a launch or a meeting with a Thai team, the table at the top is the quickest check: it shows every recurring holiday side by side across 2025, 2026 and 2027, so you can see at a glance which dates are stable and which need looking up again next year. Where a holiday falls on a weekend and is taken on another day, it appears once, on the day off, with its calendar date beside it, so the totals here match the official ones rather than double counting.
For a single year with weekday counts and long weekends, open the year page for 2025, 2026 or 2027. To compare countries in one year, the 2026 worldwide overview lists every country we cover side by side. Dates come from the open date-holidays dataset and are recalculated per year from each holiday's rule. Always confirm official dates with a local authority before you commit to travel or contracts.
